A large publishing company with multiple offices was able to cut telecom costs by using a network of Asterisk PBX servers and Polycom SoundPoint IP telephones. Each satellite office was connected using Voip to further reduce overhead. Redundant servers installed at their head offices connect corporate employees and an on-site call center to the public telephone network (PSTN) via multiple T1/PRI circuits. Remote offices connect to the corporate headquarters via an MPLS network, allowing for easy an interoffice calling and eliminating long-distance calls between offices.
Least Cost Routing
Remote offices can share T1 resources using least cost routing. Calls to/from GSM cell phones are routed via GSM/SIP gateways, making these calls mobile-to-mobile calls, which further reduces costs.
Real Time Queue Monitoring
Locations with onsite call centers benefit from integration of the Asterisk PBX platform with QueueMetrics Call Center Management Software. This software extends Asterisk’s built-in call queues (ACD) to allow for real-time queue monitoring, recording and historical analysis.
Redundant Architecture
By creating a network of Asterisk servers at each site, should a WAN connection go down, each site is able to continue independent operation. This architecture, along with server redundancy at key facilities, allowed for a high level of reliability in the system, at a price that was not achievable with proprietary telephony solutions.
